Sigmar is the warrior god of the Empire. He was the one to unite all of the tribes and create the Empire, the largest and most powerful realm of the the Old World. He held off thousands of Orcs at the battle of Blackfire Pass with the warhammer Ghal Maraz. He later wandered off into the Chaos Wastes to fight the forces of Chaos. He has not been seen since. He is now the main God of the Empire, with many temples and warrior-priests devoted to him.
